One side of the AC current at rated current ratio convert available for measurement, protection or control other equipment

The primary side AC current at rated current ratio convert available for measurement, protection or control equipment, instrumentation or protection devices used in the secondary side of the current converter equipment. The primary winding of the current transformer to  Circuit breaker , the protection or control circuit in series, the secondary winding and measuring, protection or control  air circuit breaker  to the coil current, so that the first and second side of the high and low pressure  Voltage stabilizer . When used properly, a current transformer, the ratio of the secondary rated current, and the first and second winding turns inversely. The phase difference between the current close to zero. Type according to the primary winding structure is different, can be divided through the wall, bus, cable type, casing.
